There appears to be no signs of filing or machining.  I think the wear and color match up pretty well.

And the widths are correct.  If and when I go to swap this sight I just didn't want to take someone or be taken.  I really didn't pay that much attention to the sight when I was purchasing the rifle.  Used to seeing rifle sights on fake carbines but not carbine sights on a rifle.  That just makes it a little better of a deal.  Got a Kerr No-BuckL sling with it also.

And from what I've read so far, the light loaded cast bullets aren't going to come close to matching ladder range graduations anyhow.........

Thanks,

Bob
